Hi,
I'd like to share my newest project: Helios Laser DAC. It's an USB to ILDA DAC, with fully open source hardware and software. It's low cost but still powerful with good specs: 12bit XY channels, 8bit RGBI channels, up to 65+ kpps, up to 4000+ max points in frames, plug and play automatic driver installation, aluminium enclosure etc.

I've prepared a batch and will be selling them for $89.90 each. I think that makes it the cheapest full color ILDA DAC available right now. Even cheaper than a sound card and correction amp!

Helios currently supports several programs like LasershowGen, Maxwell, LaserShow Xpress (LSX), Spaghetti, Lasercam, HE-Laserscan etc. natively, and even more have announced that they will be supporting Helios natively in the near future.
The device uses the open source libusb library for USB connectivity, which supports many platforms including Mac and Linux. I haven't built binaries for these environments yet, only windows, but I will soon, if no one else does first.
